How to Apply for Solar Subsidy in Tamil Nadu

Getting the full TN Solar Subsidy in 2026 means completing two separate processes — PM Surya Ghar central CFA and the Tamil Nadu State top-up — in the right order. For a 3 kW installation, the combined total is up to Rs.1,00,000 in direct bank credit: Rs.78,000 from the central government and Rs.22,000 from Tamil Nadu state. This guide walks through all 11 steps from PM Surya Ghar portal registration to state DBT reconciliation.

The amounts for 1, 2 and 3 kW and what you pay after both subsidies are on our rooftop solar subsidy page; this page is only about the process.

Phase 1: Central CFA — PM Surya Ghar Scheme (Steps 1–6)

Step 1: Register on PM Surya Ghar Portal (On or After 05.08.2026)

Register on pmsuryaghar.gov.in on or after 05.08.2026. Earlier registrations do not qualify for the revised CFA amounts. Keep these documents ready: EB Number, Phone No, Email ID, Customer Photo, Bank Passbook or Cheque leaf, Aadhaar, PAN, and House Tax Receipts.

The most critical rule: the consumer name on your EB bill must match your bank account name exactly — one spelling difference will get your subsidy returned by the system.

Step 2: DISCOM Feasibility Approval (TNPDCL Load & DT Check)

TNPDCL checks your sanctioned load and the capacity of the Distribution Transformer (DT) in your area before approving. Enter: State → District → DISCOM → EB Service Number → Fetch Data. Then on the My Application page: choose Residential, enter Latitude & Longitude, upload last 6-month EB bills, and submit. TNPDCL auto-approves feasibility.

Step 3: Installation via Empanelled Vendor (DCR / ALMM Modules Only)

DCR (Domestic Content Requirement) and ALMM-listed solar panels are mandatory. Non-DCR panels mean the subsidy is rejected at source. RK Solar Solutions installs only DCR compliant, ALMM-certified solar panels as an empanelled solar vendor on PM Surya Ghar.

After installation, upload on the portal: National Consumer Vendor Agreement (on Rs.100 stamp paper), GPS plant photo, DCR Certificate, and Inverter Serial Number.

Step 4: Net Metering & Commissioning (TANGEDCO Solar Net Metering Application)

The TANGEDCO solar net metering application process: apply for Net Meter on the TNPDCL portal → make payment → inform your AEE (section office) for a site inspection → AEE inspects the installation → a PCR upload link is sent to your registered mobile → upload: plant photo + Net Meter Agreement + DCR Certificate on the TNPDCL portal → Net meter is fixed → AEE approves the inspection online. The charges and export rates that apply once the meter is running are in our net metering rules guide.

Step 5: Submit Bank Details & CFA Claim (Aadhaar-Seeded Account)

Your bank account must be Aadhaar-seeded before submitting. MNRE pays via DBT only to Aadhaar-linked accounts. Non-seeded accounts are automatically rejected by the system. Fill bank details on the PM Surya Ghar portal. Account verification must show “Successful” before submitting.

Step 6: RECL Releases Central CFA (DBT: Rs.30,000 / Rs.60,000 / Rs.78,000)

RECL checks EB consumer name, Aadhaar, and bank details. Credit arrives within 15 working days. Check your PM Surya Ghar application status at pmsuryaghar.gov.in → My Application. EB name and bank name must match 100%.

*Central subsidy as per PM Surya Ghar: Muft Bijli Yojana guidelines. TN State top-up as per G.O. (Ms) No. 102 dated 19.09.2026.

The Crucial Gate: Central CFA Credited?

The PM Surya Ghar portal verifies the RECL credit and only then pushes your data to TNGECL. This gate controls the start of Phase 2 — no central CFA credit means no state subsidy trigger. If credit is delayed, contact the PM Surya Ghar helpdesk with your Application Number. For full details on the state scheme: View G.O.102 Details →

Phase 2: Tamil Nadu State Top-Up Subsidy (Steps 7–11)

Step 7: Beneficiary Data Transfer to TNGECL

After the central CFA is credited to your account, the PM Surya Ghar portal automatically pushes your verified bank details to TNGECL via an internal MIS API. No action needed from the consumer at this stage.

Track your state subsidy status at tnsolarhomes.tn.gov.in — the official Tamil Nadu State portal for the top-up disbursement.

Step 8: Eligibility Screening (Residential — First 1 Lakh Beneficiaries)

TNGECL matches your PM Surya Ghar data with the TANGEDCO portal. It confirms eligibility for solar panel subsidy in Tamil Nadu by checking: residential category, kW slab, and whether your application falls within the first 1,00,000 eligible beneficiaries from the state allocation.

Step 9: Sanction by TEDA

TEDA (Tamil Nadu Energy Development Agency) processes the funds from the Rs.50 Crore state allocation for all eligible consumers. This is an internal government step — no consumer action required.

Step 10: State DBT to Beneficiary (Rs.5,000 / Rs.10,000 / Rs.22,000)

The TN State subsidy is transferred via DBT to the same bank account where your MNRE central CFA was credited:

• 1 kW system — Rs.5,000
• 2 kW system — Rs.10,000
• 3 kW and above — Rs.22,000

Step 11: Reconciliation if DBT Fails

If DBT fails — wrong IFSC, closed account, or name mismatch — TEDA starts a reconciliation process. Contact TEDA or TNGECL with corrected bank details. Re-credit happens in the next disbursement cycle. Grievance: pmsuryaghar.gov.in → Help & Support.

How to Check Your Subsidy Status

Central subsidy: log in at pmsuryaghar.gov.in and open My Application. The page shows the stage your application has reached; the subsidy claim is the last stage. Once the claim is verified, RECL releases the amount to your bank account within 15 working days.

Tamil Nadu top-up: the state amount is tracked separately at tnsolarhomes.tn.gov.in. It starts only after the central credit is confirmed (Step 7 above), so a state entry that has not appeared yet usually means the central payment is still pending.

If nothing moves after 15 working days: check the two things that hold most claims: the consumer name on the EB bill and the bank account name must match exactly, and the bank account must be Aadhaar-seeded. If both are correct, contact TEDA or TNGECL as described in Step 11. Installers can see the same stages on the vendor side of the portal, so ask your installer to check before you travel to an office.
